The Michigan WMD, includes four waterfowl production areas (WPAs): The 160-acre Schlee WPA and 137-acre Mahan WPA in Jackson County, the 77-acre Kinney WPA in Van Buren County and the 160-acre Edgar WPA in Barry County. All are open to hunting. Although the Michigan WMD was established to increase duck breeding habitat in the Great Lakes area, the WPAs are open for hunting deer, upland birds and upland game in accordance with Michigan regulations. Use of non-toxic shot is required. In contrast with the surrounding agricultural lands, the grasses and wildflowers of Michigan's WPAs provide dense nesting cover for mallard, blue-winged teal and other grassland nesting birds. The wetlands offer excellent habitat for raising duck broods. In the fall ducks are found in the Schlee and Kinney WPAs, providing good hunting opportunities.
